Apparently the GHC runtime does something like

This is not a complaint, I find the behavior quite reasonable and much more predictable than the default (why should I not be able to catch EPIPE and continue?).
The question is whether it is documented how the GHC runtime treats signals and if yes where?
In the case of SIGPIPE, the relevant documentation can be found in:
https://downloads.haskell.org/ghc/latest/docs/users_guide/exts/ffi.html?high...
Thanks for both of your answers. The location in the docs is a bit obscure, I wouldn't look for it there, but at least it is documented. For posterity, what GHC runtime does is to install a do-nothing handler, rather than set it to SIG_IGN. This is so that this setting won't be inherited by child processes (as it would be with SIG_IGN).
